This is a "I am wondering" question and not a challenge. When I operated absorbsion refrigerators down here, they would light off and go to High Burner" 24/7
The cooling units never burned out. As a pure emergency measure I did install a mechanical AC refrigerator thermostat with the thermocouple about 6" away from the cooling fins. Being it was 2,000 miles to the border there was little choice in the matter. It lasted as long as I was in the area which was about two and a half months as I recall.
The hazard of cooling unit burnout is something new to me. When I was fighting the Norcold it was almost 30 years ago. Have things changed?
The poster that warned about overheating. Yes, it is possible. NOT LIKELY even bypassing the controls. Both Dometic and Norcold have overtemp discs on the burner casing cover that will shut off 12 volt power IF the unit overheats. The unit will overheat ONLY if the rear backside ventilation is blocked. But wiring direct will bypass that 12 volt safety control. A LOT of refers operate 24/7 because of high outside ambient temps and opening and closing the doors. The refers NEVER reach to set temp because of this. They do NOT overheat or cause a failure unless they leak or operate off spec level or the ventilation gets blocked. Doug
